A drug that good tends to sell itself.

There will be those that don’t change their practice ever once they graduate (seen a few).

Things get more complex when you have dozens of treatments for a condition with no clear winner.

I appreciate how you said “tends to sell itself”.

Before I got in the industry I thought “what the hell does marketing do?”. Then once I saw what they do, I realized, no, most drugs don’t sell themselves, there is too much inertia for doing the same old thing.

The key word was good drugs tend to sell themselves.

If you develop yet another blood pressure drug or cholesterol drug and want GPs to prescribe it, you're going to have an uphill battle.

A blockbuster drug for HepC (where treatments before weren't particularly effective and had ugly side effects) will have a much easier time becoming well known amongst the specialists that treat the disease.

Do you think there could be a substantial time lag in that case though? Sure, some movies become hits with no marketing, but DiCaprio, Brad Pitt, Ana Margo Robbie have been everywhere to market a movie with stellar reviews and a top director. Maybe that is a poor analogy. I’m not in the pharma industry, but to me, I’d hold my doctor accountable for prescribing me something I saw in a tv commercial, or not doing the legwork to understand why it could be a beneficial drug.
